    • A homologous series of n-alkyl trimethylammonium bromide surfactants, H(CH2)(n)N+(CH3)(3) Br-, from C(10)TAB to C(18)TAB have been studied systematically in the bulk over a wide range of temperatures. Common features in the structures are identified, with packing dominated by the co-ordination of the cationic head groups with bromide anions and interdigitation of the hydrocarbon chains. This arrangement provides an explanation for the thin adsorbed bilayers that have been observed at various hydrophilic surfaces from aqueous solutions in previous studies. The molecular volumes and arrangement are comparable with structures of a number of different self-assembled amphiphiles. For these surfactants with bromide counter-ions, formation of crystal hydrates was not observed. The alkyl chains are highly mobile and at high temperatures a plastic phase is found for all materials with a transition enthalpy that is similar to the melting enthalpy of many long alkyl chains. Other unexpected phase transitions depend more markedly on the hydrocarbon chain length and evidently depend on delicate balances of the various contributions to the free energy.

    • Rationale: The aim of the ALICE (Airflow Limitation in Cardiac Diseases in Europe) study was to investigate the prevalence of airflow limitation in patients with ischemic heart disease and the effects on quality of life, healthcare use, and future health risk. Objectives: To examine prebronchodilator and post-bronchodilator spirometry in outpatients aged greater than or equal to 40 years with clinically documented ischemic heart disease who were current or former smokers. Methods: This multicenter, cross-sectional study was conducted in 15 cardiovascular outpatient clinics in nine European countries. Airflow limitation was defined as post-bronchodilator FEV1/FVC less than 0.70. Measurements and Main Results: Among the 3,103 patients with ischemic heart disease who were recruited, lung function was defined for 2,730 patients. Airflow limitation was observed in 30.5% of patients with ischemic heart disease: 11.3% had mild airflow limitation, 15.8% moderate airflow limitation, 3.3% severe airflow limitation, and 0.1% very severe airflow limitation. Most patients with airflow limitation (70.6%) had no previous spirometry testing or diagnosed pulmonary disease. Airflow limitation was associated with greater respiratory symptomatology, impaired health status, and more frequent emergency room visits (P < 0.05). Conclusions: Airflow limitation compatible with chronic obstructive pulmonary disease affects almost one-third of patients with ischemic heart disease. Although airflow limitation is associated with additional morbidity and societal burden, it is largely undiagnosed and untreated.
